No blooms on the apple trees

This has been a growing problem... Apple trees that used to have tons of blooms now don't have hardly any. The apple leaves have been hard hit lately with some sort of fungus. I was thinking that the two are related. As the fungus has been more prevalent, the blooms have been less so.

Last year, half way through the growing season, I started to spray the apple trees with a copper based anti-fungal. The leaves started growing out better. Next year I plan to spray anti-fungal starting from before the first leaves emerge to see if the following year, a healthier tree can produce a healthy bloom.

What do you think?

Perhaps more fertilizer?

I have citrus trees in pots that I overwinter in my living room. I had not put fertilizer on them this year. My Meyer lemon and Limequat have suddenly both budded/flowered in the five weeks since I applied a good dose of fertilizer.

A distinct possibility.
